Do you have a question about the Ezviz T51C and is the answer not in the manual?

The EZVIZ Temperature & Humidity Monitor is a smart home device designed to detect and display indoor temperature and humidity. It integrates with the EZVIZ smart home ecosystem, sending real-time data to a linked EZVIZ gateway and allowing users to view this information on their mobile phones via the EZVIZ app. Beyond simple monitoring, it can trigger other EZVIZ smart products, enabling automated smart home scenarios.

Function Description:

The primary function of the EZVIZ Temperature & Humidity Monitor is to measure and display ambient temperature and humidity. The device features a screen that shows the current temperature (in °C by default, switchable to °F) and humidity percentage, along with a signal icon and electric quantity indicator. It communicates with an EZVIZ Zigbee Smart Gateway, which then relays the data to the EZVIZ Cloud, making it accessible through the EZVIZ app. This real-time data access allows users to monitor their indoor environment remotely. A key feature is its ability to trigger alarms if temperature or humidity levels exceed user-defined thresholds, providing timely notifications. The device supports two performance modes: Normal Mode and High-performance Mode, which can be switched by quickly pressing the button twice.

Important Technical Specifications:

Working Temperature: -10℃ to 60℃
Working Humidity: 0% to 99%RH
Wireless Protocol: ZigBee 3.0
Battery Type: CR2450
Battery Duration: Approximately 12 months
Dimensions: (Implied from images, a compact circular device)
Connectivity: Requires an EZVIZ Zigbee Smart Gateway for internet access and app integration.
Materials: (Implied from images, plastic casing with internal electronic components)

Usage Features:

Real-time Monitoring: Displays current temperature and humidity on its screen and transmits data to the EZVIZ app via a linked gateway.
App Integration: Users can view historical data, set alarm thresholds, and manage device settings through the EZVIZ app.
Unit Switching: A short press of the button allows switching the temperature display between Celsius (°C) and Fahrenheit (°F).
Performance Modes: Supports Normal Mode and High-performance Mode, selectable via a double-press of the button.
Smart Home Automation: Can be configured to trigger other EZVIZ smart products based on temperature or humidity changes, enabling automated actions like turning on a humidifier or air conditioner.
Easy Setup: The device can be added to the EZVIZ app by scanning a QR code or through the gateway's device adding mode.
Flexible Placement: Can be placed on a desktop or mounted on a wall using the included 3M tape. It is recommended to install it on a wall next to a door, avoiding metal surfaces to prevent ZigBee signal attenuation.
Gateway Proximity: For optimal performance, the monitor should be placed as close to the gateway as possible during setup and within 20m for general operation (with no more than two walls between them).
Multi-device Support: For larger homes (over 200 square meters), multiple monitors can be purchased for a better user experience.

Maintenance Features:

Battery Replacement: The device uses a CR2450 Lithium ion Battery. Users can easily remove the rear cover by rotating it anticlockwise to access and replace the battery. The manual provides detailed instructions for battery installation and replacement, including safety warnings regarding incorrect battery types, disposal, and extreme temperature exposure.
Insulation Strip: A battery insulation strip needs to be removed during the initial setup to activate the device.
Firmware Updates: The manual advises users to ensure they have the latest version of the EZVIZ app for optimal functionality, implying that app updates may include improvements or new features for the monitor.
Technical Support: In case of improper functioning after battery replacement or network configuration issues, users are advised to contact EZVIZ technical support.
Cleaning: Before sticking the 3M tape, it is recommended to swipe dust from the installation surface to enhance stickiness.
Environmental Considerations: Users are advised not to install the monitor in environments with corrosivity or intense magnetic fields to ensure longevity and accurate readings.
End-of-Life Disposal: The manual includes detailed information on the separate collection of waste electrical and electronic equipment, emphasizing that the device should not be disposed of with unsorted municipal waste. It also highlights the importance of deleting personal data from waste equipment before disposal.
